Ferroresonance Survivability of Under-Oil Arresters

Extend the research performed in Phase 1B to perform a more in-depth evaluation of arrester survivability when exposed to amorphous-core three-phase transformer ferroresonance, and in particular to assess the performance of under-oil arresters in this condition. Create guidelines indicating the range of application parameters for which an under-oil arrester can be expected to survive extended exposure to amorphous transformer ferroresonance.
